Friction welding is a very simple process.
Two items to be welded together are fitted in the machine. One remains stationary while the other rotates. They are pressed against each other at high pressure. This causes friction, resulting in the materials quickly turning plastic and achieving a temperature of between 1000 and 1100 degrees.
Because of the pressure, material is pushed out at the sides – this is the weld bead, which can subsequently be removed. When the bead is removed, the strength of the weld is not reduced, as the items are welded together throughout their surfaces – from centre to outer diameter.
Friction welding is a traditional, proven technique which has the advantage that the final weld is often stronger than the materials themselves. Our tensile tests confirm this.
It is a little funny when you consider that what we are doing is actually the same thing that our forefathers did when forging. The technique yielding the strongest union was actually invented back then.
- Environmentally friendly welding – no emissions and consumption
- Hygienic welding – more attractive end product without holes, cracks and pores
- Electronic monitoring – with documentation options and 100% traceability
- Less processing – of end product
- All-mechanical process – fewer production errors
- Less material consumption – money saved
- Strength – stronger and more durable than ordinary welding
- Fewer labour costs – on average, friction-welded items require 20-60% less processing time
- Food industry – the high hygiene and environmental friendliness of the end product provide easier access to new target groups that place high standard requirements on the product and focus on cost reduction
- Wind turbine industry – great opportunities in this segment, where strength combined with less maintenance and general savings are obvious selling points
- Industrial production – for subsuppliers to companies manufacturing products where material mix, flexibility and strength are important parameters
- Contractor machinery – the flexibility and material options, as well as the savings inherent in those options, make friction welding the obvious choice
